Answer:

f(x)=-11\times(7^x^-^1)

Step-by-step explanation:

Stare at the numbers. Especially the first two. First one is -11. Second is -11\times 7. Let's guess you keep multiplying. -77\times 7=-539. Smells correct, let's confirm with the last one: -539\times7 = -3773. I think we found a pattern. Each element is 7 times the previous one. With some practice you can just write the function, else let's divide by -11 away and let's see what we get:

f(1) = 1=7^0; f(2)=7; f(3)=7^2; f(4)=7^3. Basically, the exponent is 1 less than the value we're evaluating the function. That leads tho the following

f(x)=-11\times(7^x^-^1)

A shipment of 105 Otter box covers for I-phones has arrived. The total invoice (excluding tax, shipping, etc.) is $3,849.75.
bezimeni [28]
<span>3,849.75 </span>÷ 49.95 = 77 (Calculator)

Sense you would like it explained than the question is asking how many otter box Defender Covers where shipped in that price. So when you have that they want the amount of Otter Box Defenders than you divide the amount paid for the shipment with the amount of the otter box defender price.

I hope this is helpful.
